I've configured NG (guest manager account) and an iPad to run Aerohive Kiosk app. I can sign and go through the registration process. However, when the app gets to "Requesting secure Wi-Fi credentials" it fails with an authentication error: "purpose is required". When I checked NG no user had been created. I can see a "Purpose field" in NG when I log in using the Guest Manager account and manually create a user. However, it's not mandatory. I've been through the process on the iPad a few times and cannot see a "purpose" field on any of the screens. Any ideas?
